FEED-CUTTER.

:EJ'PECIFICATIOIQ' forming part of Letters Patent No. 313,662, dated March 10, 1885.

Application filed December 1, 1863.

.To aZZ whom it may concern.-

Be it known that I, ABRAHAM M. Fonnns TER, of Racine, in the county of Racine, and in the State of Wisconsin, have invented certain new and useful Improvements in Feed- Cutters; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to improvements in feed-cutters, and will be fully described hereinafter.

In the drawings, Figure 1 is a broken side elevation of a portion 'of a feed-cutter fitted with my improved feed-regulator. Figs. 2, 3, and 4 show details.

A is the frame; 13, the feed-box, andOis the fly-wheel keyed on the end of driving-shaft D, mounted in proper bearings of said frame. Said shaft D has a double crank on the flywheel end and a single crank, a, on its other end, and on said cranks are hung the upper ends of pitmen E and E, in the lower ends of which is journaled the bar b, supporting the sliding cutter-frame.

Fastened onto the end of the shaft F of the lower feed-roller, F, is the ratchet-wheel f, and hung on said shaft F,between the ratchetwheelf and the side of the feed-box B, is the pawl-carrier G,which is provided on the outer face of its rear end with an irregular flange, o. The first half of said flange has a slotted ear, 0,wherein the lifting-pawl dis suitablyhinged. The outer half of said flange is curved up forward and provided with an oblong vertical slot, 6, in which plays the lower end of a rod, H. This rod-is perforated to carry the stoppin 71, which bears against the under side of the flange which has the slot 6. The upper end of said rod H passes up through a sleeve, 2', formed on the lower end of thebar I, wherein it is held in proper adjustment by means of the set'screw z". The pawl-carrier G has atits front end the finger It, which oscillates on the outer face of the plate J. This plate,which is the feed-regulator, has the stop-lug k and the open slotm, whereby and by means of the bolt 12 and of the nut o the regulating-plate may be given the adj ustment desired. Aspiral spring, p, suitably attached to the under side of the carrier G and to the frame A, is designed to bring down the carrier and pawl cl after every successive upstroke of the rod H.

Hung on a suitable bracket, 8, fastened on (No mull-l.)

the side of the feedbox B, is the stop-pawl 0",

which engages with the ratchet-teeth and prevents the lower roll from turning backward after having been moved forward by the lifting-pawl d of carrier G.

The operation ofiny feed device is as follows: The crank-shaft D being rotated,every downstroke of the crank lowers the rod H, and the spring 1) causes the carrier Gto follow the stoppin h on the lower end of said rod H, and the phiint of pawl 0Z- slips over the teeth of the ratchet. The upstroke of the crank raises the rear end of the carrier G, and the pawl d engages with the ratchet f and turns the feedroller F.

I have shown two ways of adj ustingthe feed, one of which is the shortening or lengthening ofthe rod H by sliding it more or lessinto the sleeve 6 of the hinging-bar I, wherein it is secured by the set-screw z". The pawl d is thus made to engage with more or less teeth of the ratchet. The other adjustment, which as the first may be used independently, is effected by means of the removable plate J, in which case the number of teeth of the ratchetf with which the pawl d will engage will be determined by the position given to the said plate J by the fastening-nut 0 of bolt a.

Graduated lines 1 2 3, as shown on face of plate J and rod H, may be provided to serve as guides for the adjustment required.

In Figs. 3 and 4 is shown theilnproved construction of my teedrollers. They are made of staves or sections NN, the ends of which are fastened and held together around the hubs llI. These hubs are provided on their outer faces with a wide flange, 1), through which open slots :1: w are cut, wherein screwbolts 2 z, passing through said staves N, are held in place by the nuts :4 z. Said hubs M may be made with a central square hole to fit on the square shaft of the roller, or they may be keyed on a round shaft, as desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is'

l 1. In a feed-cutter, the lifting-rod H and devices eonnected thereto, ratchet-w heel f, rollershaft F, and carrier G, having finger Iain combination with the graduated plate J having lug k and an open slot, m, and with bolt a, nut 0, and the pawl r, as set forth.

In a feed-cutter, the combination, with the 1", and spring 19, as set forth.

ratchet 'wheel f, shaft F, and the carrier G, ed as shownand described, and for the purpivo'ted on said shaft, and having a slot, 6, of pose set forth. pawl d, finger 7c, link I, sleeve 2', set-screw i, In testimonythatIclaimthe foregoinglhave lifting-rod H, provided with stop-pin h, plate hereunto set my hand, at Racine, inthe county 5 J, having the slot and securing devices, pawl i of Racine and State of Wisconsin, in the pres- I I ence of two witnesses.
